Frequently asked questions
What supply voltage range does the MKL03Z32VFK4 operate over, and does the 105°C rating hold in a sealed industrial panel?
The part operates from 1.71V to 3.6V — this comfortably spans 3.3 V nominal rails. The 105°C absolute maximum rating applies at the package level; thermal resistance of the 24-QFN joint to ambient and your enclosure airflow determine whether you actually get to 105°C TA at full load in a sealed panel. The exposed pad ties to VSS for thermal relief, so solder it down properly to realise the thermal performance the rating assumes.
